Financial functions


NumPy has a number of financial functions, as follows:

  • The fv function calculates the so-called future value. The future value gives the value of a financial instrument at a future date, based on certain assumptions.

  • The pv function computes the present value. The present value is the value of an asset today.

  • The npv function returns the net present value. The net present value is defined as the sum of all the present value cash flows.

  • The pmt function computes the payment against loan principal plus interest.

  • The irr function calculates the internal rate of return. The internal rate of return is the effective interested rate, which does not take into account inflation.

  • The mirr function calculates the modified internal rate of return. The modified internal rate of return is an improved version of the internal rate of return.

  • The nper function returns the number of periodic payments.

  • The rate function calculates the rate of interest.
